CLASP.

Application led September 28', 1927. ySerial N0. 222,670.

My invention relates to clasps in general, and particularly the necklace clasps, the 0b-` ject being to provide in such a clasp a ring relatively stationary with the adjacent bead, thereby rendering the clasping of thel necklace more easily and rconveniently accomplished. I accomplish this object by means of the'construction illustrated in the accompanying drawing, which is al part of this application for Letters Patent, like characters of reference indicating like Lparts throughout the several views thereof, and in which,- l

Fig. 1 is a sectional View of a necklace end with my invention applied thereto.

Fig. 2 is a view similar to Fig. 1 butV of the subject In general my invention consists of aY ring with an extension integral therewith and adapted for insertion within the bead adjacent the clasp, and means upon said stem for passing a cord therethrough.

In its preferred form the stem 9 is provided with twin channels 10 oppositely disposed upon the stem and extending theentire length thereof, and being sufficiently large to receive the cord upon which the necklace beads are strung. The ring 11 is rigidly integral with the stem 9, and at the juncture of the stem and said ring I provide a notch 12 as shown in detail in Fig. 5, to receive the cord as it turns upon itself at the ring 11. rIhe split ring 13 of the Aclasp engages the ring 11 in the usual manner.

The result of this construction is thatthe ring 11 remains in fixed relationship with the adjacent bead, that relationship being such that the engagement of the ring with the split ring 13 is most easily accomplished,

while with ordinary construction kas usually followed in commerce the ring 11 falls back upon the adjacent bead and thereby renders clasping the ends of the necklace diiiicult.

The stem 9 may be cut short of the diametrical length of the bead, as shown in Fig.l 1, or when hollow beads are heilig strung it may be left to project into the second bead, as shown in Fig. 2.

The cord is passed along one of the channels 10, over the notch l2 and along the other channel 10, the cord and the stem then being` inserted into the bead kas shown in F 3. i

Otherk methods'4 of securing the ycord to the device may lie-used, as for example the `modilication shown in F ig'. 7, wherein the stem is hollow, and the cord is passed over a transverse pin 15 at the outer end of the hollow stem. A further modification adapted to the use Vof a single cord is shown in F ig. 8, wherein a hollow stem is provided with a socket 16 adapted to receive a knot in the cord. v

My invention may be made of any size, and constructed of any materials deemed convenient and suitable fora device of this character', and while I have illustrated a form of my invention found desirable in materializing` my invention, I wish to include in this application all mechanical equivalents and substitutes that may fairly be considered to come within the scope and.

. purview of my invention as defined in the appended claim.

Having disclosed my invention so that use the same, what I claim as new, and desire to secure by Letters Patent is:

In a necklace clasp: a ring; a stem rigidly integral with said ring; twin channels `PATENT OFFICE.

.others may be enabled to construct and to oppositely disposed upon said stem to receive cord; and a notch connecting said channels at the junction of said ring and said stem.

In witness whereof I claim the foregoing as my own I hereunto aflix myy signature at Portland, county of Multnomah, State of Oregon, this 25th day of May, 1927.
